The fact that the author of Henry’s book is being mentioned makes me think that the showrunners may be in the know about the show coming to an end perhaps as early as S4. The reveal of the author’s identity has always seemed like a final-season kind of reveal. Also, if a spoiler is to believed that Emma’s heart becomes frozen (I know, how original), then I really hope it’s not a romantic true love’s kiss that thaws her out. (We already saw what happened when Emma’s lips were pressed to Hook’s cursed lips in S3b). Rather it’d be nice to see a kiss or act of true love from HENRY–you know, Emma’s confirmed true love. Frozen is all about family love being important. It would also be a nice inversion from the S1 finale when Emma saved Henry. Let Henry be the hero! The kid hasn’t gotten to do anything even remotely heroic since he nearly got himself killed in S3a. The kid still has the Heart of the Truest Believer and may even have magic of his own, since you know, his parents also had confirmed true love.
